Abstract
To examine at one-year follow-up the efficacy of an internet-based intervention for infant and toddler sleep disturbances, as well as to assess any indirect benefits to maternal sleep and confidence. Participants included 171 (64.8%) of 264 mothers of an infant or toddler (ages 18-48 months) who had previously participated in a 3-week study. Families had been randomly assigned to one of 2 intervention groups (algorithmic internet-based intervention alone or in combination with a prescribed bedtime routine) or a control group. After a one-week baseline, the intervention groups followed personalized sleep recommendations. The initial internet-intervention was found to be efficacious at 2 weeks post-intervention. The current study investigates a one-year follow-up, with mothers completing a short survey that included 8 questions from the Brief Infant Sleep Questionnaire and 1 question from the Pittsburgh Sleep Quality Index. Improvements in difficulty falling asleep, number/duration of night wakings, and longest continuous sleep period were maintained at one year follow-up in the 2 intervention groups compared to baseline and end of the initial study, p < 0.001. Children in the control group, in which limited changes were seen in the initial study, showed improvements in the duration of night wakings and longest continuous sleep period compared to the end of the initial study. Mothers in all groups were less likely to describe their child's sleep as a problem. These results suggest that a brief internet-intervention for early childhood sleep problems is effective in improving child and maternal sleep, with improvements maintained one year later.
